George Oliver Walsh, Count of Wallis (German: Georg Olivier Graf von Wallis, Freiherr von Carrighmain; 1671, in Vienna – 19 December 1743, in Vienna) was a field marshal of Irish descent in the service of the Holy Roman Empire and the Kingdom of the Two Sicilies and last regent of the Habsburg Kingdom of Serbia (1738–1739). Born into an exiled Irish family, he distinguished himself in Sicily by his capture of Messina. He then commanded on the Rhine (1733), then in Italy and Hungary. He lost the decisive Battle of Grocka against the Ottoman Empire in 1739, thus leading to the peace of Belgrade, which was unfavourable to Austria and thus led to his disgrace.
